QCE PhysicsPractice Examination 10

This paper covers

• Unit 4 quantum theory anchored on de Broglie electron diffraction through a crystal lattice and comparison to X-ray Bragg diffraction
• de Broglie wavelength from accelerating voltage, momentum and kinetic energy of accelerated electrons
• Bragg's law nλ = 2d sinθ: multi-order diffraction, electron vs X-ray diffraction angles, crystal lattice spacing determination
• photoelectric effect (work function, threshold frequency, stopping voltage, Planck gradient from KEmax-frequency graphs)
• Bohr hydrogen atom: energy levels, transition energies and emission wavelengths
• Unit 4 special relativity: time dilation, length contraction, mass–energy equivalence
• Standard Model: quark composition, conservation laws in particle decays, exchange bosons
• Unit 3 gravity: Newton's Law of Universal Gravitation, gravitational field strength, Kepler's third law, satellite and geostationary orbital mechanics
• Unit 3 electromagnetism: Coulomb's Law and electric fields, work on charges, the motor effect, electromagnetic induction (Faraday/Lenz), transformers and power transmission
• Assessment Objectives 1-4: describe/explain, apply/calculate, analyse evidence, interpret/justify/evaluate with full evidence-principle-conclusion reasoning chains
